Overview
Plantar fasciitis is a condition that causes pain in the bottom of your foot, especially near the heel. It happens when the thick band of tissue (called the plantar fascia) that runs along the bottom of your foot becomes irritated or inflamed.
Key facts
- It is one of the most common causes of heel pain.
- The pain is often worst with your first steps in the morning.
- Most people improve with simple treatments within a few months.
Yes, plantar fasciitis is very common, especially among people who spend a lot of time on their feet.
It can affect anyone, but it is more common in people between the ages of 40 and 60, those who are overweight, and those with jobs that require standing or walking for long periods.
Symptoms
- Severe pain that makes it impossible to walk.
- Signs of infection in the foot, such as redness, warmth, swelling, or fever.
- Sudden swelling or bruising after an injury.
- ⚠Pain that does not improve with rest and simple home care after a few weeks.
- ⚠Inability to bear weight on the foot.
- ⚠Numbness or tingling in the foot.
Common symptoms
- Sharp or stabbing pain in the bottom of the foot near the heel.
- Pain that is worst when you take your first steps in the morning.
- Pain that gets better after walking for a while but may return after long periods of standing or sitting.
Symptoms in children
- Plantar fasciitis is less common in children. If a child has heel pain, it may be due to growth spurts or other conditions. Always have a doctor evaluate foot pain in children.
Symptoms in older adults
- Pain may be more constant and take longer to heal. Older adults may also have other foot conditions, like arthritis, that can add to the discomfort.
Causes
Main causes
- The plantar fascia becomes stretched or strained, leading to tiny tears and inflammation.
- Repeated activities that put stress on the heel and attached tissue, such as running, dancing, or standing for long hours.
Risk factors
- Being overweight.
- Having a job that requires standing for long periods.
- Having tight calf muscles or a tight Achilles tendon.
- Wearing shoes with poor arch support or thin soles.
- Having flat feet or high arches.
When to see a doctor
See a doctor urgently if:
- Sudden, severe pain after an injury.
- Signs of infection, like redness, warmth, or fever in the foot.
- Numbness or tingling in your foot.
Book a routine appointment if:
- Pain that lasts longer than a few weeks despite home treatment.
- Pain that makes it hard to do your daily activities.
Diagnosis
Your doctor will ask about your symptoms and examine your foot. They may press on different areas to find where it hurts and check your foot's movement and strength.
Tests that may be done
- Usually no tests are needed. Sometimes an X-ray or ultrasound may be ordered to rule out other problems like a stress fracture or arthritis.
What to expect at your appointment
The diagnosis is often straightforward based on your history and physical exam. Your doctor will explain the condition and recommend a treatment plan.
Treatment
Treatment focuses on reducing pain and inflammation, and then stretching and strengthening the foot and calf muscles. Most people get better with simple steps.
Self-care at home
- Rest your foot as much as possible.
- Apply ice to the painful area for 15–20 minutes several times a day.
- Do gentle stretches for your calf and the bottom of your foot.
- Wear supportive shoes with good arch support.
- Consider using over-the-counter heel pads or shoe inserts.
- Avoid walking barefoot on hard surfaces.
Medical treatments
If self-care is not enough, your doctor may suggest physical therapy, custom orthotics (insoles made to fit your feet), or treatments like shockwave therapy. In some cases, steroid injections may be offered, but these are used with caution. Always follow your doctor’s advice.
When is surgery considered?
Surgery is rarely needed and is only considered after all other treatments have been tried for many months without success. It involves releasing the tight plantar fascia.
Living with this condition
You can manage plantar fasciitis by wearing good shoes, stretching regularly, and icing after activity. It may take weeks to months to fully heal, but you can still do most activities with some adjustments.
Lifestyle tips
- Wear supportive shoes with good arch support.
- Avoid high heels or flat shoes that lack cushioning.
- Use a frozen water bottle to massage your foot while icing.
- Do daily stretches for your calves and the bottom of your foot.
Diet and exercise
Keeping a healthy weight can reduce strain on your feet. Low-impact exercises like swimming or cycling are easier on your feet while you recover. Stretching your calves and the plantar fascia is very important.
Mental health and emotional wellbeing
Chronic foot pain can be frustrating and may affect your mood and sleep. It is normal to feel this way. Be patient with the healing process and talk to your doctor if you feel down.
Prevention
You can lower your risk by wearing supportive shoes, maintaining a healthy weight, and doing regular foot and calf stretches. If you run or exercise, increase your activity level slowly.
Complications
If left untreated
- Chronic heel pain that may make walking difficult.
- You may change the way you walk to avoid pain, which can lead to problems in your feet, knees, hips, or back.
- The plantar fascia may tear.
Long-term outlook
Most people with plantar fasciitis recover fully with simple treatments. It can take several months, but patience and consistent care usually lead to a good outcome.
